Pointing and calling is a method in occupational safety for avoiding mistakes by pointing at important indicators and calling out the status. It is common in Japan and railways of China.

We investigated the self‐regulatory strategies people spontaneously use in their everyday lives to regulate their persistence during aversive activities.

Amazon Aurora is a relational database service for OLTP workloads offered as part of Amazon Web Services (AWS). In this paper, we describe the architecture of Aurora and the design considerations leading to that architecture. We believe the central constraint in high throughput data processing has moved from compute and storage to the network. Aurora brings a novel architecture to the relational database to address this constraint, most notably by pushing redo processing to a multi-tenant scale- out storage service, purpose-built for Aurora. We describe how doing so not only reduces network traffic, but also allows for fast crash recovery, failovers to replicas without loss of data, and fault-tolerant, self-healing storage. We then describe how Aurora achieves consensus on durable state across numerous storage nodes using an efficient asynchronous scheme, avoiding expensive and chatty recovery protocols. Finally, having operated Aurora as a production service for over 18 months, we share lessons we have learned from our customers on what modern cloud applications expect from their database tier.

What is the role of PgBouncer in a Postgres High Availability stack?

Here, we illustrate use of DTrace on a host system to observe activity within a Docker container, running on Oracle Linux using runC.

This talk investigates fake science factories; international twilight companies whose sole purpose is to give studies an air of scientific credibility while cashing in on millions of dollars in the process.

Streaming replicas—and by extension, base backups—can become dangerously broken when the source and target machines run slightly different versions of glibc.

The principal–agent problem, in political science and economics, occurs when one person or entity (the "agent") is able to make decisions and/or take actions on behalf of, or that impact, another person or entity (the "principal")

The ongoing competition between IPv4 and IPv6 has big implications for the future of the internet. Is this mixed-standard Internet a passing phenomenon, or will we get stuck in it?

Though Blockchain has been touted as the answer to everything, a study of 43 solutions advanced in the international development sector has found exactly no evidence of success.

Malware and other applications may install persistent keyboard "event taps" to intercept your keystrokes.
ReiKey can scan, detect, and monitor for such taps!

PostgreSQL is the database management system that gained more popularity in our DB-Engines Ranking within the last year than any of the other 343 monitored systems.
We thus declare PostgreSQL as the DBMS of the Year 2018.

In this results book, we would like to present this out- standing research, publishing more than 110 reports on projects carried out in 2016 and 20171. Our “TOP 5” pro- jects in terms of allocated core-hours consumed 17% of the total available core-hours on SuperMUC in this time- frame and merit special mention:

1. Astrophysics: Janka et al. performed longtime 3D su- pernova simulations (page 32)
2. Computational Fluid Dynamics and Engineering: Lohse et al. performed simulations on thermal turbulence at extreme Rayleigh numbers (page 108)
3. High Energy Physics: Jansen et al. studied nucleon ob- servables as probes for physics beyond the standard model (page 202)
4. Earth, Climate and Environmental Sciences: Ludwig et al. research climate change and hydrological extremes (page 185)
5. Astrophysics: Dietrich et al. investigated binary neu- tron star mergers (page 18)
